In my case, I never did acknowledge the OW. It is about you and the W.
I remember reading a great quote from Spencer Tracy's wife when she met Katharine Hepburn for the first time: I thought you were just a rumor. LOL!!
To show W that you're detached, you can respond to her text as in "sure thing...no problem. have a good day!" The key thing in your interactions with W going forward is friendly and cordial. She's made her choice and needs to live with it for a while.
The main focus is rebuilding your relationship with your sons. It is about making them happy, feeling valued, and being able to trust you once again. What does that look like to you? Dig deep and you'll see the answers right inside you all along.
